It takes a lot to get red carpet ready even if you are People's Most Beautiful Woman in the World. But when Gwyneth Paltrow wore a see-through dress to the Iron Man 3 premiere this past week, she had to go to some very extreme measures.

"I kind of had a disaster," Paltrow, 40, told Ellen DeGeneres on her talk show. "I was doing a show and I changed there, and I went and I couldn't wear underwear. I don't think I can tell this story on TV. Well, let's just say everyone went scrambling for a razor and so I went from being the most beautiful to the most humiliated in one day."
